Detailed Description

The scope of the present invention is not limited to the specific language used in the description of the embodiments or illustrations, and the same reference numbers may be used in the embodiments. When a component is "connected to" or "coupled to" another component, it can be directly connected or coupled to the other component or intervening components may be present.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

Fig. 1A is a schematic diagram of an adapter according to an embodiment of the invention. Fig. 1B is a schematic diagram of the adapter of fig. 1A from another perspective. Fig. 2 illustrates an exploded view of the adapter of fig. 1A. FIG. 3 is a schematic view of the driving member of FIG. 2 from another viewing angle. Referring to fig. 1A, fig. 1B, fig. 2 and fig. 3, the adapter 100 of the present embodiment mainly includes a receiving member 110, a driving member 120 and a plurality of electrical connecting members 130. In the embodiment, three electrical connectors 130 are taken as an example for illustration. In other preferred embodiments, the number of the electrical connectors 130 is not limited. In addition, the electrical connectors 130 are plugs corresponding to various specifications of power sockets, for example.

In the present embodiment, the driving member 120 has a driving unit 121, and the driving unit 121 has a first electrical connection portion 126. In addition, the accommodating part 110 has a first configuration space S1 and a plurality of second configuration spaces S2. Referring to fig. 4, fig. 4 is a schematic diagram illustrating the driving member of fig. 1A with the first surrounding surface and a portion of the first connecting surface removed. In the present embodiment, the first disposition spaces S1 are suitable for disposing the driving unit 121, and the second disposition spaces S2 are suitable for disposing the plurality of electrical connectors 130. The number of the second disposition spaces S2 corresponds to the number of the electrical connectors 130, for example.

The driving member 120 includes, for example, a first surrounding surface 123 and a first connecting surface 124. The first surrounding surface 123 is located at an outer edge of the first connection surface 124, and the driving unit 121 is located between the first surrounding surface 123 and the first connection surface 124. The first connection surface 124 exposes the first electrical connection portion 126 of the driving unit 121. In addition, the accommodating element 110 includes, for example, a second surrounding surface 112 and a second connecting surface 113. The second surrounding surface 112 is located at an outer edge of the second connection surface 113. The second surrounding surface 112 and the second connecting surface 113 form a first disposing space S1 and a second disposing space S2. In the present embodiment, the accommodating member 110 further includes a separating structure 115, for example. The separating structure 115 is further adapted to define a first disposing space S1 and a second disposing space S2 by a space surrounded by the second surrounding surface 112 and the second connecting surface 113.

Particularly, the driving member 120 of the present embodiment is sleeved on the accommodating member 110 along an actuating axis L, so that the driving member 120 can slide relative to the accommodating member 110 along the actuating axis L. In detail, the accommodating element 110 of the present embodiment is, for example, a base, and the driving element 120 is, for example, a cover. The cover can cover the base and can move along the actuating axis L relative to the base. Further, when the driving unit 121 is withdrawn from the first allocation space S1 and is no longer limited by the accommodating element 110, the driving element 120 can also rotate about the axial direction L. Therefore, the present embodiment can easily switch the adapter 100 from a storage state convenient for the user to an operation state connected to the power supply by actuating the driving unit 121. Of course, the adapter 100 of the present embodiment can have a thinner volume for the user to operate even in the operating state.

In detail, in the accommodated state of the adapter 100 (as shown in fig. 1 and 4), the accommodating element 110 and the driving element 120 are sleeved with each other, the driving unit 121 is disposed in the first disposition space S1, and the plurality of electrical connectors 130 are disposed in the corresponding second disposition spaces S2. Fig. 5A to 5C and fig. 6A to 6C are also referenced, in which fig. 5A to 5C are schematic diagrams illustrating the adapter of fig. 4 being converted from the storage state to the operation state, and fig. 6A to 6C are schematic diagrams illustrating the operation process of the adapter of fig. 5A to 5B after the accommodating member is removed. During the process of the adapter 100 from the storage state (as shown in fig. 1 and 4) to the operation state (as shown in fig. 5C), the driving member 120 can move along the actuating axial direction L toward the direction D1 away from the accommodating member 110 (as shown in fig. 5A and 6A), so that the driving unit 121 can be withdrawn from the first disposition space S1.

As mentioned above, after the driving unit 121 is withdrawn from the first disposition space S1, the driving member 120 can be rotated about the axial direction L (as shown in fig. 6A and 6B), and the first electrical connection portion 126 of the driving unit 121 is electrically connected to one of the electrical connection members 130 (as shown in fig. 5B and 6C). The angle of the driving element 120 rotating around the actuating axis L is, for example, such that the driving element 120 is effectively connected to an electrical connector 130 after rotating. Thereafter, the driving element 120 can move toward the direction D2 of the accommodating element 110 to make the driving unit 121 enter the second configuration space S2 configured by the electrical connector 130, so as to withdraw at least a portion of the electrical connector 130 (as shown in fig. 5C). In other words, the adapter 100 shown in fig. 5C is in an operation state capable of connecting with an external power socket (not shown).

In addition, in the embodiment, the first connection surface 124 is provided with a first through hole set 125, for example, and an external terminal (not shown) is adapted to penetrate through the first through hole set 125 to be connected with the first electrical connection portion 126. The first through hole set 125 is, for example, a universal jack, and the external terminal is, for example, a plug terminal of an electronic device. On the other hand, the second connection surface 113 may be provided with a plurality of second through hole sets 114 (as shown in fig. 1B), for example, each second through hole set 114 corresponds to one electrical connection 130. In addition, the electrical connector 130 has, for example, a second electrical connection portion 131 and at least one electrical terminal 132. The electrical terminals 132 are electrically connected to the second electrical connection portions 131. In detail, the positions and shapes of the openings of the second through hole sets 114 correspond to the electrical terminals 132 of each electrical connector 130, for example. In this way, when the driving unit 121 of the driving element 120 enters the second arrangement space S2 where the electrical connector 130 is arranged, the electrical terminal 132 of the electrical connector 130 can be withdrawn from the corresponding second through hole set 114 to the outside of the accommodating element 110, so that the electrical terminal 132 is connected to the external insertion hole. The external jack is located on a power socket (not shown), for example.

Fig. 7 shows a partial cross-sectional view of an adapter according to an embodiment of the invention. Fig. 8 is a schematic view of an electrical connector according to an embodiment of the invention. Referring to fig. 7 and 8, the driving member 120 may further include a first engaging portion 127, and each of the electrical connectors 130 may include a second engaging portion 133. In the storage state, the first engaging portion 127 is located at the bottom of the driving unit 121. On the other hand, the second engaging portion 133 is located on the top of each electrical connector 130. In the operating state, the driving member 120 moves along the operating axis L to exit the first allocation space S1, and then rotates around the operating axis L. Therefore, the first engaging portion 127 rotates to a limiting space S4 of the second engaging portion 133. In other words, the driving element 120 rotates to mutually engage the first engaging portion 127 and the second engaging portion 133, so that the driving element 120 can stably withdraw the electrical terminal 132 of the electrical connector 130 out of the accommodating element 110. The first engaging portion 127 and the second engaging portion 133 are made of a non-conductive material, for example.

In addition, in a preferred embodiment, the second electrical connection portion 131 is a conductive protrusion, and the first electrical connection portion 126 has a conductive recess 126 a. In an operation state, during the process of engaging the driving member 120 with the electrical connector 130, the conductive protrusion of the second electrical connection portion 131 is tightly fitted with the conductive recess 126a of the first electrical connection portion 126. In this way, the first electrical connection portion 126 of the driving unit 121 can be effectively and stably electrically connected to the electrical connection member 130.

In addition, in the present embodiment, a limiting protrusion (not shown) may be disposed on an inner wall of the second surrounding surface 112 of the accommodating component 110. Therefore, in the accommodated state, the electrical connector 130 can be interfered with the position-limiting protrusion through the second engaging portion 133 to be limited in the corresponding second disposition space S2. In an operating state, the electric connector 130 can be pushed by the driving unit 121 to remove the interference with the limiting protrusion, and then smoothly exit out of the accommodating member 110. Of course, after the electrical connector 130 is withdrawn out of the accommodating element 110, the driving unit 121 may also pull the electrical connector 130 back to the second configuration space S2 by the engaging relationship between the first engaging portion 127 and the second engaging portion 133, and the electrical connector 130 is retained in the corresponding second configuration space S2 by the interference between the second engaging portion 133 and the retaining protrusion.

Further, in the present embodiment, the receiving member 110 has a shaft hole 111, the driving member 120 has a pivot 122, and the pivot 122 can be disposed in the shaft hole 111 along the actuating axis L. Therefore, the driving member 120 can be effectively sleeved on the accommodating member 110 along the actuating axis L and rotate around the actuating axis L. In other preferred embodiments, the receiving member 110 may be provided with a pivot, and the driving member 120 may be provided with a shaft hole, which is not limited herein.

On the other hand, in the present embodiment, a third disposition space S3 may be disposed between the first surrounding surface 123 and the first connection surface 124. Therefore, in the accommodated state, the third disposition spaces S3 may overlap with the second disposition spaces S2. In other words, in the accommodated state, the electrical connectors 130 may be simultaneously located in the third configuration space S3. In the operating state, since the driving unit 121 has exited from the first configuration space S1 and entered into a second configuration space S2, the third configuration space S3 in the operating state overlaps with the first configuration space S1 and a portion of the second configuration space S2.

Fig. 9 is a flow chart illustrating a method of using the adapter according to an embodiment of the invention. Referring to fig. 9, the method of using the adapter of the present embodiment includes the following steps: first, in step S110, an adapter in a storage state is provided. The adapter has the accommodating member, the driving member and the plurality of electrical connectors as described above. In addition, the accommodating piece is provided with a first configuration space and a plurality of second configuration spaces. The driving member is sleeved on the accommodating member along an actuating axis and has a driving unit. The driving unit is provided with a first electrical connection part. The driving unit is configured in the first configuration space, and the electric connectors are configured in the second configuration spaces.

After the step S110, step S120 is performed to drive the driving element to move along the actuating axis toward a direction away from the accommodating element, so that the driving unit exits from the first configuration space. Then, step S130 is performed to drive the driving member to rotate around the actuating shaft and connect with one of the electrical connectors. Then, step S140 is performed to drive the driving member to move toward the accommodating member. Then, step S150 is performed to drive the driving unit to enter the second configuration space configured by the electrical connector, and to exit at least a portion of the electrical connector to convert to an operating state.

In summary, in the adapter of the present invention, in the accommodated state, both the driving unit and the electrical connector are located in the accommodating element, and the driving element and the accommodating element are completely sleeved (as shown in fig. 1A). Therefore, the adapter of the invention has better containing function, so that the adapter is convenient for users to carry. In addition, the adapter of the present invention can be converted from the storage state to the operation state through a simple sliding and rotating procedure. In other words, the adapter of the present invention has the effect of convenient operation.

In addition, after the adapter is converted into an operating state, the terminal of the electrical connecting piece to be used can be withdrawn out of the accommodating piece by the driving unit so as to be electrically connected with an external power socket. The plug terminal of the external electronic device can be electrically connected with the terminal of the electrical connector to be used by being inserted into the first through hole group, and is electrically connected with an external power socket through the electrical connector so as to obtain a power supply.

It should be noted that after the adapter of the present invention is converted into the operating state, only the terminal of the electrical connector to be used will be withdrawn out of the accommodating member, and the driving unit and other electrical connectors are still located in the accommodating member. In other words, even if the adapter of the present invention is in an operating state, the adapter still maintains a better storage function and has a thinner volume for the user to operate.

The above description is only an example of the present invention, and is not intended to limit the present invention, and it is obvious to those skilled in the art that various modifications and variations can be made in the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
